Insert Block into Text/Attribute

I'm trying to insert symbols (such as an "EIT" inside a hexagon) into the attribute of my block. Anybody know of a way to insert a block as text in an attribute so that symbol will follow the attribute through rotations, movements, etc.?

You cannot insert a block (A) into an attribute of another block (B).

You can write a custom LISP routine which inserts A into the drawing, and programmatically extracts needed value from A, and modifies B attribute with said value, then deletes A... But that is just cumbersome, and more complicated then it needs to be.

If you know the possible values, then hard-code those values as options into a custom routine which allows you to select B, and select an option (A value?) to apply to B's attribute. Does that make sense?

You can make the attribute move and rotate together inside a block with dynamic blocks. Does that help?
